Hij zegt toch ook dat hij een dagje El Hierro gaat doen?
Ofwel, niets wijst erop dat de uitbarsting voorbij is.quote:As a matter of fact, most eruptions are preceded by earthquakes, but in most cases the earthquakes stop once the eruption has reached a stable regime. The stopping of earthquakes does not mean that the eruption will stop anytime soon, the eruption might continue for years after the end of significant earthquake activity. Earthquakes are indicative of breaking rocks, caused by magma pushing into areas where there is no established conduit.
Once a stable magma flow occurs through a well-established conduit, there will be no longer any earthquakes.
The cessation of earthquakes only means that the situation has somehow stabilized, not that magma is ceasing to flow.
The real indicator of continued magma flow is volcanic tremor.
Only once the volcanic tremor disappears, then one might reasonably argue that the eruption is over.

volgens mij nog 150 meter hoor...quote:Op maandag 12 december 2011 12:14 schreef 1boefje het volgende:
Jaja dit klopt wel:
. The webcam also shows regular white patches
Enig idee hoe ver de vulkaan nu onder het oppervlakte ligt?
Laatst wat ik gelezen heb was 70 meter.
ergens stond dat er vanaf nu ongeveer 8 weken nodig was om dat stuk te overbruggen. Dus tenzij je zwaar terminaal bent zou het evenuteel nog wel binnen je levensverwachting mogen gebeuren ;-)quote:Op maandag 12 december 2011 13:12 schreef 1boefje het volgende:

quote:- if the same process continues for about 3 to 4 weeks and in the same vent we expect regular hydrovolcanic explosions during the bursts.
- if the same process goes on 5 to 6 weeks the eruption may become Surtseyan. This is the most spectacular phase of the eruption. During this phase of the eruption ash and steam clouds can reach hundreds of meters to several km in height. Particular to Surtseyan eruptions are the thick,dark-pointed jets of fragments, often headed by bombs, shot out of the vent.
- if the same process goes on 7 to 8 weeks and in the same vent, the eruption will have created at least a new island

- As we are currently in a submarine eruption phase with hydromagmatic bursts, we have searched and found a scientific study about such action. In 1984 Kenneth H. Wohletz and Robert McQueen from the USA Los Alamas National Laboratory wrote a paper with the title : “Experimental Studies of Hydromagmatic Volcanism“ [PDF]. We encourage people who want to learn more details about the current phenomena, to read (at least some parts) of this article.

Mooi plaatje van vanmorgen dus.quote:Update 12/12 -14:58 UTC
The amazing NASA Satellite MODIS picture taken at 11:55 UTC this morning (3 hours ago) is showing a cloud column on the exact place of the vent towards the island. Even we do not believe it ! Is must be a coincidence and if not than we have detected the steaming vent waters. The image cannot have been photoshopped as it has been extracted directly from the NASA website (thanks to Julio del Castillo Rivero for sending us the NASA link).
